Not in Northern AK, but present in Fairbanks and further south

Probably easier to find in Fairbanks/south, but there's a report from ANWR too (Eastern Brook's Range). Present down into the 48 too, but not CA.

Only iNat reports are by Whitehorse (YT) and Cambridge Bay (Nunavut) but I bet that shit's in the North Slope somewhere
